[TRNSYS-users] Photovoltaic Pumping

[David BRADLEY]

Sergio,
   Type194's power outputs are in units of W while Type794 wants its 
inputs in kJ/h so you have to put an equation between the two models to 
convert the units manually. You cannot simply change the units of the 
Type794 input in the proforma in your project. Doing so does NOT make 
any kind of unit conversion; it affects only the input initial value.
Kind regards,
  David
